Abstract

Lay Summary Density-dependent differences between dispersing and non-dispersing birds in mass and fledging success were observed in control but not food-supplemented nests. Density-dependent differences in oxidative state were however not altered by the supplementation. Our results support the hypothesis that food availability is responsible for some of the density-dependent differences previously observed in this natural population between dispersing and non-dispersing individuals but other mechanisms are also involved in these differences.
